The last time the public saw Casey Anthony, she was rocking a svelte look and a new bob. Photo:

Casey Anthony is reportedly fat and looking for a one-way ticket out of town!

The infamous Florida “Tot Mom” has been hiding in plain sight, having gained so much weight she’s “unrecognizable,” according to RadarOnline.

A source tells the gossip site that Anthony “hasn’t needed to wear a disguise because of the physical transformation. Casey is finding comfort in food and she is clearly eating a lot.”

The source said Anthony is spending her time renting DVDs and getting takeout.

“She is very careful to not linger anywhere when she does and tries not to make eye contact with anyone.”

Anthony, who beat the rap 11 months ago in connection with the murder of her 2-year-old baby Caylee, can’t leave the Sunshine State for now because she’s serving probation for writing bad checks.

But once that legal shackle is removed later this summer, Anthony reportedly wants to bolt, perhaps to Costa Rica.

“Casey is counting the days until her probation ends. She has been researching countries that she could move to and Costa Rica is at the top of the list,” a source close to the situation told Radar.

“Casey wants to live in a warm tropical setting and the cost of living is extremely low in Costa Rica. She wants to put as much distance as possible from Florida. Costa Rica appeals to her because Americans are warmly embraced by the locals, and she feels this is the best place to start a new life.”
